All systems are go for Jake Arrieta to make his Opening Day start next Monday against the Angels after he left his last spring outing early with a blister on his pitching thumb.

Arrieta threw 46 pitches in a bullpen session Sunday morning. He and his manager declared him ready to go.

"He was fine," Cubs manager Joe Maddon said. "No restriction whatsoever. He felt great. It was like it never happened. I anticipate no problems."
